access.

3.Roll the timing belt off the top large end pulley and rest it on the smaller pulley, as shown in Figure 81.

4.Loosen the pivot lock bolt shown in Figure 81, then turn the spindle counterclockwise by hand as you apply pressure to the direction gear pivot bracket until both grease fittings are accessible for lubrication.

5.Add lubricant and wipe of any excess lubricant.

6.Rotate the direction gear pivot bracket so that the direction gears correctly mesh with the spindle shaft gear for your next operation, then re-tighten the pivot bolt.

7.Apply upward and forward pressure to the top end pulley to tension the timing belt as you re-tighten the tensioning thumb screw to secure it in place.

Important: Leave a slight amount of slack in the timing belt. Adjusting the tension too tightly will cause excessive wear and stretching.

Adjusting the tension too loosely could cause the timing belt to slip during operation.

8.Close the end cover before re-connecting the lathe to power.
